String.split() 测试

1、去掉所有 ：

    public static void main(String[] args)
    {
        String str = "A
B
c";
        String[] strs = str.split("[
]+");
        for (int i=0; i<strs.length; i++)
            System.out.println(strs[i]);
        
        System.out.println("");
        
        str = "Ac

B1

c2";
        strs = str.split("[
]+");
        for (int i=0; i<strs.length; i++)
            System.out.println(strs[i]);
    }

输出为：

A
B
c

Ac
B1
c2

2、

代码：

    public static void main(String[] args)
    {
        String str = "a c v  f   b       t  ";
        String[] strs = str.trim().split(" +", 3);
        System.out.println("strs.length(1) : "+strs.length);
        for (int i=0; i<strs.length; i++)
            System.out.println(strs[i]);
        
        System.out.println("");
        str = "a cccccc";
        strs = str.trim().split(" +", 3);
        System.out.println("strs.length(2) : "+strs.length);
        for (int i=0; i<strs.length; i++)
            System.out.println(strs[i]);
    }

输出：

strs.length(1) : 3
a
c
v  f   b       t

strs.length(2) : 2
a
cccccc

C
